Background technology
According to existing technical level, known have a diversified automatic open-end spinning machine.In Rieter Ingolstadt spinning machinery is made the handbook " RotorspinnerR40-Roboter " (open-end spinning frame R40-automatic machine) of joint-stock company, such automatic open-end spinning machine has just been described, it be arranged in can be vertically along overlapping on the attending device that spinning machine moves.When preparing repiece, the yarn end that will be wound on the bobbin by a loose thread suction nozzle sucks, and is stretched between the yarn treatment device of attending device.In order to be placed on the bare bobbin, attending device has an auxiliary bobbin and other yarn treatment device, and yarn just is stretched between the described yarn treatment device.There is a yarn trap to receive the yarn that is tensioned, and it is passed to a yarn feeding assembly.The yarn feeding arrangement of components can move linearly on attending device, and has a yarn binding clasp, by yarn trap yarn is penetrated described yarn binding clasp.Then, yarn is cut off, and spins processing before carrying out for repiece.In this case, to be stretched in all the time between the clamp of loose thread suction nozzle and yarn feeding assembly by the yarn of repiece.Therefore, when the yarn feeding assembly was done linear yarn feeding campaign, relative motion just took place in yarn in clamp, this may be in continuing processing initiating failure or in the finished product yarn, cause defective.In addition and since the yarn treatment device on bare bobbin the geometric position during repiece with respect to broken yarn after the geometric position difference of yarn treatment device when putting, therefore be difficult to make the yarn feeding assembly to reach best alignment with respect to the yarn treatment device.The draw-off mechanism that the yarn of repiece penetrates free-end spinning machine again also can make yarn produce relative motion in the clamp of yarn feeding assembly, and this equally also can cause fault.
According to DE 35 15 765 C2, the same known automatic open-end spinning machine that has on a kind of free-end spinning machine.At this, different with above-mentioned prior art level, the yarn feeding assembly is rotatable on bearing position, to such an extent as to the yarn feeding campaign can be carried out on a circuit orbit.Fixing a lever jack in rotating mode on the turning arm of yarn feeding assembly, described lever jack also is connected with the shell of spinning-in system with the fixing coupling part of hinging manner by one, and can control so as to making it to become.Revolution fortune by the yarn feeding assembly is the upset lever jack outwards, so that be yarn guide, and spins assembly before yarn passed to yarn.After spinning before yarn, the yarn feeding assembly continues to turn to the direction of spinning organ, and simultaneously, lever jack is subjected to the control of coupling part horizontal in the yarn feeding assembly, and yarn is penetrated the draw-off mechanism of spinning organ thereupon.When the gyration of yarn feeding assembly finished, clamp was positioned in the top of spinning apparatus, and threw in yarn.Do not address the storing on bare bobbin in the patent specification.On said apparatus, may be because produce the relative motion of yarn in clamp with the geometrical arrangements yarn feeding assembly and rotatable coupling part that can the revolution mode supports.
Summary of the invention
Task of the present invention is, the relative motion of the yarn of avoiding repiece in the yarn feeding assembly and the problem that takes place during repiece and on the bare bobbin that is placed to the time behind broken yarn because of this relative motion.
Above-mentioned task is utilized independently, and feature described in the claim solves.
A kind of automatic yarn spinning-in system on the spinning organ of free-end spinning machine, have one and be used for spinning assembly before with the yarn that carries out repiece cut off and before spin processing by the yarn end of repiece, and a yarn feeding assembly that utilizes turning arm and binding clasp the yarn end of repiece to be directed to spinning organ.On the yarn feeding assembly, arranged a thread-carrier.According to the present invention, in the yarn feeding motion process that is arranged in whole thread-carrier yarn guiding assembly of thread-carrier with the turning arm of yarn feeding assembly on binding clasp keep invariable distance, therefore, kept invariable basically by the yarn end of repiece position with respect to binding clasp in whole yarn feeding motion process.According to the present invention, but the thread-carrier that is used for guiding the repiece yarn end is fixed and arranged on automatic open-end spinning machine on the free-end spinning machine, and keeps invariable distance with respect to the binding clasp on the turning arm of yarn feeding assembly in the whole yarn feeding motion process of yarn feeding assembly.
By according to the present invention with the thread-carrier fixed and arranged on a turning arm of yarn feeding assembly, make yarn from leave thread-carrier and begin same motion process to realize being placed on the bare bobbin and broken yarn after the repiece process.Therefore, the geometric position of yarn treatment device no longer influences the position of yarn in clamping device.Can avoid whereby the yarn feeding assembly is expended very big adjustment work.In addition, because thread-carrier is on the constant point of substantially constant, therefore can optimize the location of yarn with respect to clamping device.Like this, in the yarn feeding motion process, can avoid the relative motion of yarn in thread nipper assembly basically.Thereby reduce to continue the fault in the process and improve yarn qualities.Equally also can optimize yarn with respect to by the location of repiece yarn end transport.
If thread-carrier is arranged on the swivel point of turning arm of yarn feeding assembly basically, then hardly length variations can take place at the yarn end between thread-carrier that is stretched in the yarn feeding assembly and the clamping device in whole yarn feeding motion process.This measure equally also helps avoid the relative motion of yarn in yarn feeding assembly clamping device.
According to another preferable formation scheme of the present invention, the yarn feeding assembly can turn round around a trunnion axis.Can make the yarn feeding assembly on attending device on the spinning organ or movably, realize the layout that helps saving the locus like this.But also it is contemplated that and allow the yarn feeding assembly turn round around a vertical axis.
Described device preferably has a yarn trap, will spin assembly and/or yarn feeding assembly before being sent to yarn by repiece and the yarn of being derived the coil of yarn end as having.For this reason, to be preferably on the bearing position be rotating to yarn trap.
In addition, preferably thread-carrier has an otch with fixing yarn end of being derived.In this case, thread-carrier is to arrange like this, is promptly derived the gyration of yarn end by yarn trap and slides in the otch of thread-carrier, and be fixed at this place.Like this, two yarn end of yarn coil can be separated with simple method, so that easily the yarn end of repiece is cut off and before spin processing.
In addition, according to an embodiment that the spy is good of the present invention, thread-carrier has one and is applicable to by the sliding edge of repiece yarn end.Wherein, sliding edge is to constitute like this, promptly when yarn trap carries out gyration, is slided along sliding edge by the yarn of repiece, further separates with two one threads of supporting yarn coil.At this moment, sliding edge and otch are located on thread-carrier like this, and promptly corresponding yarn end successively arrives otch or sliding edge successively.
Another formation design for scheme of the present invention is predesignated, and sliding edge is to by the yarn of repiece certain laterally offset effect being taken place.Like this, might allow yarn penetrate in the draw-off mechanism of free-end spinning machine with simple method.
Wherein special good part is, can be arrived the sliding edge of thread-carrier in lateral deflection by the gyration of yarn trap by the yarn end of repiece.Therefore, when yarn trap turned round downwards, laterally offset took place in yarn end automatically, so that send the yarn end of repiece to the yarn feeding assembly.
Other benefit is, by the yarn end of repiece can be by the yarn feeding assembly gyration on a position that turns back to the spinning organ middle part on the sliding edge of thread-carrier.Can accomplish that like this yarn penetrates in the draw-off mechanism of free-end spinning machine automatically in the yarn feeding motion process of yarn feeding assembly, simultaneously, yarn is walked around a hold-down roller of draw-off mechanism from the side.In this case, sliding edge designs like this, and promptly yarn slips back to its original position, spinning organ middle part automatically.
If thread-carrier is made with a kind of light sheet material, then can realize advantageous embodiment on a kind of simple and price of thread-carrier.Wherein, otch and sliding edge can be with simple method by punching press or laser formations.
But it is contemplated that equally also the another kind of material of thread-carrier is for example made with plastics or pottery.
Other benefit is that to constituting, wherein, at least one roll of roll centering is drivable to the clamper of yarn feeding assembly with a secondary roll.So can make and be returned spinning organ by the yarn end of repiece and become easier.
Wherein special good part is, thread-carrier is arranged on the straight line perpendicular to the roll longitudinal axis.Can accomplish that like this thread-carrier will be positioned on the position perpendicular to the roll longitudinal axis by the yarn end of repiece in the whole gyration process of yarn feeding assembly.If desired yarn is transmitted back to spinning organ, then loopback can not cause yarn to remake a relative motion in addition on the longitudinal direction of roll.Can also avoid damaging yarn like this and problem takes place when putting.Therefore on the roll of clamper, do not need thread-carrier.

The specific embodiment
Illustrated among Fig. 1 according to automatic open-end spinning machine 1 of the present invention, it is disposed in one movably in the attending device 2 (representing with chain-dotted line among the figure).On the right side, also show a free-end spinning machine 3 with chain-dotted line, it has many same stations 4, and described station is arranged in juxtaposition, and attending device 2 can move along these stations, so that can safeguard each station 4 wherein when needing.For this reason, attending device 2 has various instrument so that change a full bobbin with a bare bobbin (not illustrating among the figure) for example, with the yarn repiece of bare bobbin, perhaps behind broken yarn with the yarn repiece and restart the operation of spinning.According to another embodiment of the invention, automatic open-end spinning machine 1 is not to be arranged in one movably on the attending device 2, but each station 4 of free-end spinning machine 3 all has an automatic open-end spinning machine 1.
Each station 4 of free-end spinning machine 3 has an open-end spinning device 7 (chain-dotted line), wherein is provided with a spinning element, here is a spinning twisting ring 8, is rotatable and drivable.For spinning twisting ring 8 has been equipped with the fiber (not illustrating among the figure) that needs spinning, be aided with a fibre-opening unit having 9, the fiber in the ribbon that the latter feeds with known method shredding.Then, under normal operating condition, the yarn F that is spun into fiber in spinning twisting ring 8 doffs by the pipe 10 that doffs from spinning element 8 by a doffing device 11.Doffing device has driven doff a roller 12 and a non-driven hold-down roller 13, and the latter is can rotating mode being supported.In normal spinning operation duty, hold-down roller 13 is adjacent to the driven roller 12 that doffs, and therefore occupies the position of representing with the stretching, extension line.Under normal spinning running status, the motion process of yarn F is represented with a dotted line.
In draw-off mechanism, compensate camber member 14 and following a waxing attachment 15 in case of necessity along with a yarn tension at doffing device 11 heels.The yarn that is drawn out is wound on the bobbin 6 at last, and the latter is bearing on the spool stand 16.In normal spinning operation process, bobbin 6 is on the position that dots, and is driven by a bobbin roller on the direction of doffing 17, shown in the dotted line haircut.
If broken yarn, then the mechanism of station 4 shuts down with universal mode.Bobbin 6 lifts away from bobbin roller 17, and the driving of bobbin 6 is interrupted, and it occupies at last with stretching the position that the line line is represented as a result.For repiece, attending device 2 has an auxiliary drive 18, and the bobbin 6 that lifts away from bobbin roller 17 is given in configuration.Auxiliary drive 18 is gone up driving bobbin 6 in the direction (representing with solid arrow among the figure) of unwinding.In this driving process, loose thread suction nozzle 20 (dotted line diagram) is to the revolution of the direction of bobbin 6, seeks and seize to be in the lip-deep yarn end of bobbin.If the yarn F of loose thread suction nozzle 20 absorption unwinding from the bobbin 6, then it deflects into the position of representing with the stretching, extension line.Yarn F is received by another pneumatic thread processor 21 on this position, and pulls out one section out and away, and yarn F takies the position that solid line is represented at last as a result, and it is stretched between the outlet and pneumatic thread processor 21 of loose thread suction nozzle 20 simultaneously.
On above-mentioned position, yarn F is seized with the yarn trap 22 that can the revolution mode supports by one, and passes to a yarn feeding assembly 23 can the revolution mode to support equally by gyration.But yarn trap 22 spins assembly 25 before also can yarn F being passed to yarn feeding assembly 23 or pass to a yarn by linear movement.It is contemplated that equally also yarn feeding assembly 23 self also can be at the yarn F scope intrinsic deflection that is stretched between the yarn treatment device, to receive yarn F.
So yarn takies position shown in figure 2, at this moment, be stretched between loose thread suction nozzle 20, yarn trap 22 and the pneumatic thread processor 21 as the yarn F of yarn coil.Yarn coil has one by the yarn end F ' of repiece and a derivative yarn end F ", described yarn end is connected with loose thread suction nozzle 20, and is inhaled collection and processing by this loose thread suction nozzle on a time point subsequently.
Yarn feeding assembly 23 has a clamping device 24, the latter in this case by a secondary roll to constituting, it is drivable that this roll is centering to a rare roll 19.In case be clamped in the clamper 24 by the yarn end F ' of repiece, by the yarn end F ' of repiece just by the shear that do not illustrate among the figure with by the yarn end F of repiece " separate, and with known method spin before by a yarn assembly 25 carry out repiece before spin processing.Be clamped in the clamping device 24 and carry out repiece before spin gyration that the yarn end F ' of processing can be by yarn feeding assembly 23 to the spinning organ yarn feeding.At this, can support the yarn feeding campaign by the additional linear displacement of yarn feeding assembly.
When yarn trap 22 is given clamping device feeding yarn coil, must guarantee to have only to be clamped in the clamper 24 of yarn feeding assembly 23 by the yarn end F ' of repiece.
According to the present invention, there is a thread-carrier 27 to be arranged on the turning arm 28 of yarn feeding assembly 23.Thread-carrier 27 is to arrange that so promptly yarn is stretched between clamper 24 and the thread-carrier 27 in the whole yarn feeding motion process of yarn feeding assembly 23.For this reason, thread-carrier 27 is such designs, i.e. separation yarn termination F ' and F reliably " come so that they are separated from each other, and spin processing before the yarn end of repiece carried out.By the layout of thread-carrier 27 according to the present invention, constant with respect to motion process substantial constant in the whole yarn feeding campaign of yarn feeding assembly 23 of the clamping device 24 of yarn feeding assembly 23 by the yarn end F ' of repiece.
In the time of on being placed to bare bobbin, yarn is stretched between other (not illustrating among the figure) yarn treatment device with method similar but that do not illustrate among the figure, yarn is seized by yarn trap 22 at this place equally, and is brought to as yarn coil in the zone of yarn feeding assembly 23.The geometrical arrangements of other yarn treatment device is to that indicated in the drawings different, and therefore the motion process of the yarn coil of tractive also is different from the process shown in the figure downwards.But, by arranging a thread-carrier 27 according to the present invention, the yarn movement process between thread-carrier 27 and yarn feeding assembly 24 or the yarn trap 22 can realize and be placed on the bare bobbin and broken yarn after the identical yarn movement process of yarn movement process of repiece.So just need not expend very big adjustment to yarn feeding assembly 24, because irrelevant fully from the geometrical arrangements of the yarn movement process of thread-carrier 27 beginning and described yarn treatment device with respect to the different yarns processor.
At this, thread-carrier 27 also can be located like this, is promptly obtained the optimum position with respect to clamper 24 by the yarn F ' of repiece.So, in the scope of clamping device 24, just no longer need yarn is directed to other feed carrier in the clamping device 24.So basically also can avoid the relative motion of the yarn F ' that in the yarn feeding motion process, may need in other cases.
According to as can be seen shown in Figure 2, thread-carrier 27 is arranged near the swivel point 29 of yarn feeding assembly 23.The result causes by the yarn F ' of repiece very little length variations only having been taken place in rotating yarn feeding campaign (representing with chain-dotted line) process.By existing technical level, such length variations causes in the roll 19 of clamping device 24 relative motions taking place equally, this may be when putting initiating failure.Near the swivel point 39 of yarn feeding assembly 23, the length variations of yarn F ' is just more little for thread-carrier 27.
In addition, from Fig. 2, also can find out, under situation, clamped under state basically perpendicular to the longitudinal axis 30 of the roll 19 of clamping device 24 by the yarn end F ' of repiece with respect to the clamping device 24 optimal placement thread-carriers 27 of yarn feeding assembly 23.This state remains unchanged in whole yarn feeding motion process.Like this, when yarn feeding assembly 23 is turned back to string-up position when (representing with the stretching, extension line), yarn also is clamped under the state perpendicular to the roll 19 of yarn feeding assembly 23.If, must then can as the prior art level, not cause yarn F ' on the axial direction of roll, to move by vertical clamping like this via the roll 19 delivered yarn F ' of clamping device 24 in order to allow yarn F ' turn back in the spinning apparatus 7.
In illustrated embodiment, yarn feeding assembly 23 is being bearing on its position around the rotating mode of trunnion axis, and therefore, the member of spinning-in system 1 can be arranged in the attending device 2 according to the requirement of saving the space.But also it is contemplated that another embodiment, according to this scheme, yarn feeding assembly 23 can be around a vertical axis revolution.So the roll 19 of clamping device 24 is preferably taked a position perpendicular to the position shown in Fig. 1 and 2, to avoid yarn F ' in the yarn feeding campaign with turn back in the process of spinning apparatus 7 relative motion takes place again.
Spinning-in system 1 also has a secondary auxiliary roller in addition to 26, and the yarn of repiece doffs from spinning apparatus 7 to very fast through this auxiliary roller.In this case, auxiliary roller is in resting position to 26 demonstrations.By the yarn end F ' of repiece when yarn trap 22 carries out gyration, penetrate into auxiliary roller to 26 in.In the repiece process, auxiliary roller moves 26 directions along spinning organ, so that yarn is doffed soon.When yarn feeding assembly 23 carries out the yarn feeding campaign, penetrated into again by the yarn F ' of repiece in the doffing device 11 of spinning organ self, therebetween, yarn F ' must walk around the hold-down roller 13 (Fig. 4) of doffing device 11 in side direction.In case the yarn of new repiece is transferred on the doffing device 11 of station 4 of free-end spinning machine 3 again, just cancels clamping through auxiliary roller to 26, auxiliary roller turns back to illustrated position to 26.
Among Fig. 3 with perspective view show according to thread-carrier 27 of the present invention and when yarn trap 22 (not illustrating among the figure) carries out gyration yarn end F ' and F " motion process.The yarn F that is stretched between loose thread suction nozzle 20 and another yarn treatment device 21 is seized by yarn trap 22 on illustrated time point, and turns round on the direction of yarn feeding assembly 23 downwards.About yarn feeding assembly 23, shown in figure in can only see turning arm 28, at its end, thread-carrier 27 is arranged near the swivel point 29.Thread-carrier 27 has an otch 31, the yarn end F that is derived by loose thread suction nozzle 20 after can fixed random on this otch ".On illustrated time point, yarn end F " arrived the position of thread-carrier 27, and slip in the otch 31.Yarn end F ' the short time of yarn coil reaches later the position of sliding edge 32, till being taken in yarn trap 22 it slides into a set time point 33 when carrying out gyration in this position (Fig. 4).So, two yarn end F ' and F " spatially be separated from each other and come, and can guarantee to have only by the yarn F ' of repiece again and be clamped in the clamping device 24 of spinning-in system 1.So in the scope of clamping device 24, just do not need other guide or separator.
Two yarn end F ' and F when Fig. 4 shows after a while time point of arrival " the position, yarn trap 22 its gyration that has been through with has also been penetrated by the yarn F ' of repiece in the clamping device 24 of yarn feeding assembly 23 on this time point.On illustrated time point, vertically be clamped in by the yarn end F ' of repiece between the roll 19 of clamping device 24, with the same shown in Fig. 2.On above-mentioned time point, yarn end F " be arranged on the yarn feeding assembly 23 but the yarn shear that does not illustrate in the drawings downcuts by one, and inhale collection and handle through loose thread suction nozzle 20.Then, being clamped at yarn end F ' in the roll 19 spins the known method of assembly 25 usefulness before by the yarn of can't see in the drawings and attaches most importance to and spin processing before new repiece is carried out.At last, the yarn end F ' that spins processing for repiece before carrying out carries out rev motion yarn feeding by the yarn feeding assembly 23 (referring to Fig. 2) of open-end spinning device 7, and finally turns back in the spinning twisting ring 8 by blast pipe 10.
In addition, it can also be seen that in the diagram of Fig. 4 that yarn end F ' obtains a laterally offset by the gyration of yarn trap 22 on the sliding edge 32 of thread-carrier 27, up to it till being received on the fixing point 33.When yarn feeding assembly 23 carried out the yarn feeding campaign, yarn end F ' was directed into the side of the spinning organ middle part M that represents with chain-dotted line thus.In the yarn feeding motion process, the available simple method of yarn end F ' is walked around the hold-down roller 13 of the doffing device 11 of free-end spinning machine 3.Hold-down roller 13 with dashed lines figure in this case represents.If yarn feeding assembly 23 has arrived string-up position (the stretching, extension diagram among Fig. 2), then also penetrated into simultaneously in the doffing device 11 of free-end spinning machine 3 by the yarn end F ' of repiece.Therefore, yarn end F ' is slided along sliding edge 32 by the fixing point 33 outside the M of spinning organ middle part in the yarn feeding motion process, to the last arrives its home position at the spinning organ middle part again.Then, can implement the repiece process,, after successfully finishing repiece, cancel clamping to 26 therebetween by auxiliary roller with known method, yarn final then again the doffing device 11 by spinning organ self doff.
Arrange a thread-carrier 27 by the gyration of yarn feeding assembly 23 with according to the present invention, can realize the optimal movement process with respect to yarn feeding assembly 23, therefore can avoid yarn F ' relative motion in ' 24 at clamping device by the yarn end F ' of repiece.Can with loose thread suction nozzle and yarn treatment device 21 and on bare bobbin the geometrical arrangements of other yarn treatment device of repiece irrelevant, reach this optimal movement process of yarn F ' independently.In view of the above, can also obtain same yarn movement process, therefore can cancel yarn feeding assembly 23 is expended very big adjustment with respect to the yarn treatment device for the repiece that is placed to behind bare bobbin and the broken yarn.In addition, utilize, can also utilize the yarn feeding campaign of yarn feeding assembly 23 that yarn F ' is penetrated in the doffing device 11 of free-end spinning machine 3, need not to use other parts for this reason with simple method according to thread-carrier 27 of the present invention.By optimizing by the yarn movement process of the yarn F ' of repiece and avoiding the relative motion of yarn in clamping device 24, can set up the storing process more reliably, and improve yarn qualities.
The present invention is not limited to illustrated embodiment.Change in the claim scope belongs to the present invention equally.
